Mode and tempo are known to influence affective experiences during music listening. While mode (major/minor) is associated with emotional valence (positive/negative), tempo (slow/fast) is associated with emotional arousal (calm/excited). Heart rate (HR) and respiration rate (RR) are also thought to adapt (entrain) to the tempo, leading to emotion elicitation via afferent feedback mechanisms. Here, we tested the influence of mode, tempo, and entrainment on affective experiences by recording HR, RR, and self-reported subjective entrainment and affect measures while participants (N = 20) listened to major and minor chords embedded in slow and fast isochronous, metrical, and random sequences. Though there was no effect of tempo on HR or RR, both were faster during major and metrically random chord sequences, respectively. Slower HR positively predicted visceral entrainment (VE) ratings, the extent to which one feels one’s internal rhythms changing, and fast tempo positively predicted motor entrainment (ME) ratings, the extent to which one feels like moving. Compared to minor chords, fast major chord sequences induced more feelings of vitality (positive, high arousal), while minor sequences induced more feelings of unease (negative, high, and low arousal). Both ME and VE positively predicted pleasantness ratings and positive emotions, and negatively predicted negative emotions.
